Sea levels around the world are rising as a result of human-caused global warming. Overall, global sea levels have risen about 10 centimeters from 1993 to 2023, as seen in this animation. However, sea levels are also rising at an accelerating rate. Right now, global sea level rises about 0.17 inches (0.42 centimeters) per year. For comparison, the 1993 rate was 0.07 inches (0.13 centimeters) per year. “Current rates of acceleration mean that we are on track to add another 20 centimeters of global mean sea level by 2050, doubling the amount of change in the next three decades compared to the previous 100 years and increasing the frequency and impacts of floods across the world.” – Nadya Vinogradova Shiffer, director for the NASA sea level change team. Video Description: Animation of blue ocean water level rising from 1993 to 2023. A vertical line shows change in sea level in increments of 10 centimeters and 5 inches. The animation starts in 1993 and, as it continues, the water sloshes up and down but continues an overall rising trend until the animation ends in 2023. By the end, the water level has risen just over 10 centimeters from where it started. #Earth #Science #Climate #Ocean #SeaLevelRise #NASA #Data #DataVisualization #Sea #ClimateChange #GlobalWarming #WorldOceansDay #NationalOceanMonth

A £400m UK government loan to the Tropical Forests Forever Facility tightens the link between embodied carbon and real forest outcomes. Bio‑based and renewable building materials will now be judged on credible, deforestation‑free supply chains as much as on glossy lifecycle assessment or whole life carbon assessment outputs, driving wider use of environmental product declarations (EPDs), green building materials and green building products. Expect stronger traceability, circular construction strategies and end‑of‑life reuse in construction when specifying low embodied carbon materials and low carbon construction materials to cut the carbon footprint of construction and support the circular economy in construction.

Updated damp and mould guidance from the Chartered Institute of Building and the Chartered Institute of Housing reframes indoor environmental quality as a health obligation, pressing social landlords towards whole‑house ventilation, insulation upgrades and continuous monitoring. The shift embeds sustainable building design and energy‑efficient buildings as compliance issues, with implications for life cycle cost, building lifecycle performance and net zero whole life carbon pathways recognised by BREEAM and BREEAM v7.

A new retrofit procurement guide uses public spending to expand capacity, create local jobs and tackle skills shortages by baking training and labour targets into contracts. This gives sustainable construction and decarbonising the built environment delivery teeth, promoting life cycle thinking in construction, resource efficiency in construction and eco‑design for buildings, alongside sustainable material specification and low carbon building upgrades that support carbon neutral construction.

Escalating climate risks—from European wildfires to transboundary smoke and cascading Himalayan floods—are accelerating environmental sustainability in construction and sustainable urban development. Design for resilience is becoming core to net zero carbon buildings and green construction, with fire‑hardening, smoke filtration, heat‑safe interiors and green infrastructure specified to reduce the environmental impact of construction, deliver carbon footprint reduction over whole life carbon and strengthen eco‑friendly construction and sustainable architecture.
